He appears to have fully recovered from the accident, as the 27-year-old looked like his normal self as he sang a duet of Letting Go (Dutty Love) with Minaj.
"Just killed it on stage with the lovely [Nicki Minaj]," Kingston tweeted after the show. "Had an amazing time feels great to be back on stage [especially with] the hottest female out."
Minaj, who is opening for Britney Spears on her Femme Fatale tour, also gave Kingston props, tweeting: "Whoa!... [Sean Kingston] just SHUT MIAMI DOWWWN w/me at the Femme Fatale Tour!!! Thank u guys soooo much!!!!"
